Mark watched in awed surprise as his dog Rainbow suddenly flickered out of sight with a soft, audible pop.
“Did it work?” Mark wondered. He rushed about the house hurriedly looking for Jennifer.
She was no longer in the bathroom, or in her bedroom, or the living room or kitchen. Mark was in a bit of a panic and was about to give up, when he chanced to look out the kitchen window into the back yard. There was his eighteen year old sister outside on all fours with her mini-skirt hiked up above her waist and her lacy, pink panties pulled down around her ankles! Her legs were quivering and shaking slightly, and a look of intense, flushed concentration was on her face. Mark stood there and watched in abject horror as Jennifer, grunting and groaning, produced a tightly coiled, steaming pile of waste right there on the lawn!
Now finished, Jennifer, still on all fours, clumsily pulled back up her panties and pulled back down her skirt. She then turned around and proudly began sniffing at her odoriferous, still warm, accomplishment.
